When changing the colour of a clothing item, especially the plain colours, this permanently damages this piece of clothing.
For example: When changing the colour of a pair of trousers I found in a chest somewhere to blue, the whole thing becomes plain blue. The trousers themselves, but also the belt, the holster, the kneepads and associated belts of those.
And I cannot change it back to its original colour without then everything becoming that colour instead.

When changing colours, belts, holsters and kneepads should not also change.
